My guess would be pH paper!
Universal indicator is used to determine the pH value over a wide range. It is used in tit-ration experiments too.
The nature of the solution be it acidic or basic will determine the PH value of the given solution.
It depends on the concentration, but a 1 molar solution will have a pH of 0
When an universal indicator solution is added to the alkali it turns to BLUE.pH value of alkali is 10 and 11.
The pH value of the solution depends on the strength of the acid, in other words, acid concentration.
It depends on what indicator you use. An alkaline solution will have a pH-value >7. So if you're using BTB, it'll be blue. If you're using Fenolftalein, then it'll be pink.
The pH value is an indication of the acidity/alkalinity of a solution. More precisely, the pH value is a representation of the concentration of hydrogen cations (hydronium ions) in a solution.
Hydrochloric acid cannot be assigned a pH value. pH is a measure of the hydrogen ion concentration in an aqueous solution, not the strength of an acid. Because hydrochloric acid is a weak monoprotic acid the pH of a solution of it is fairly easily calculated. pH=-log[HCl], where [HCL] is the concentration of the hydrochloric acid in moles per liter.
what is the Ph of a solution containing 5mg/L of hydrochloric acid?
because it as actually an indicator not a solution
Well, Blackcurrant juice would be seen more of an actual indicator than a solution. I suggest you use a different solution that has a higher acidic or alkaline scale.
It neutralises. For instance if you have hydrochloric acid and add universal indicator, then add sodium hydroxide (alkali) it turns green. (pH value 7, neutral).
It doesn't matter how much you have, HCl (Hydrochloric Acid) has a pH of 1
You need solution to determine value.
When it is not mixed with any other solution, it is green. Green represents neutrality, so its pH is 7.
Its Ph value is less than 7, so it is acidic. The exact colour change needs to be compared visually with a standard universal indicator chart to determine the precise Ph value associated with that particular shade of red.
Litmus only differentiates between acidic and alkaline solutions. It does not give an accurate value of the degree of acidity of alkalinity. Universal Indicator can help measure the pH of the given solution as it does not just change from red to blue and vice versa, but in solution has a range of colours.
The pH is the measure of the hydrogen ion activity in solutions. The value of pH determine the acidity or alkalinity of a solution.
An indicator is a chemical compound which change the color depending of the value of the pH.
Percent error is typically used to describe the difference between an expected value and an observed value (measured in an experiment). To calculate percent error, you must know the expected (or theoretical) value, determined from reference manuals and formulas. Percent error = [(actual measured value)/(expected value) - 1] x 100% Let's say that you do a chemistry experiment, where you expect to use 30 mL of a hydrochloric acid solution to neutralize a prepared solution of sodium hydroxide. When you perform the experiment, you actually use 30.2 mL of hydrochloric acid solution. Percent error = [(30.2 mL) / (30 mL) - 1] x 100% = 0.667 % error
it tell u the pH value that color is change according to acid base indicator.
if something is and indicator, then it will be able to proove to you wether a substance is acid or alkali. here are some common lab indicators used to determine the Ph value of some substances. remember, pH 1-6 is acid ph7 is neutral and pH 8-14 is alkali -Litmus paper is red in a neutral solution, red in an acid and blue in an alkaline solution -Universal indicator is is green in a neutral solution, red, orange or yellow in an acid and blue or violet in an alkali -Phenolpthalein is colourless in a neutral solution, colourless in an acid and pink inn an alkal -Screened methyl orange is orange in a neutral solution, red for pH below 3.6, orange for pH above 3.6 and yellow in an alkaline solution
pH 1 to 2.
